How do I remove The Coolant Level Sensor

My coolant level sensor is bad., how do I replace it? I understand that there is a retaining metal wire holding it on. How do I get that wire off?

Just lift one leg of the retainer, twist and pull the sensor out of the radiator. Twist it about 90deg.

Also, look at the new one.....you will get an idea how the retainer works.....might need a coolant flush.....if you have contaminated fluid, that would cause sensor failure.....and cause the new one to fail too....
